五种类型树木前景广阔
Five types of trees have broad prospects
今年东北绿化随着工程量的增加，对苗木有很大需求，其中，我认为五个品种前景最广阔。一是乡土树种东北地区很多乡土树种因生长慢、繁殖难，常都被忽视而一些城市建设部门盲目引进外来树种，更是走入了绿化误区。如今，很多人开始将目光转向乡土树种，如大叶朴、小叶朴、辽东栎、蒙古栎以及一些槭树科乡土品种，这些树种适应性强，将在绿化中唱主角。
With the increase of engineering quantity, there is a great demand for seedlings in Northeast greening this year. Among them, I think five varieties have the widest prospect. First, native tree species. Many native tree species in Northeast China are often ignored because of slow growth and difficult reproduction. However, some urban construction departments blindly introduce foreign tree species, which leads to the misunderstanding of greening. Nowadays, many people begin to turn their attention to native tree species, such as magnolia, Magnolia, Quercus liaotungensis, Quercus mongolica and some Aceraceae native species, which have strong adaptability and will play a leading role in greening.
二是观花小灌木以及观果苗木。城市要真正靓丽起来，少不了应用有花的植物来进行点缀，像山桃、山杏山梨、山楂等观花时间长的小乔木在绿化泥杆 保定空压机 保定古筝 塑料增韧剂 拱形护坡模具 保定空调维修 托辊设备  托辊生产线市场上不可或缺。而一些观果的乔木品种如忍冬等如能进行适当应用绿化效果则更丰富。
The second is small shrubs and fruit seedlings. If a city wants to be really beautiful, it is necessary to use flowering plants to decorate it. Small trees with long viewing time, such as peaches, apricots, pears and hawthorn, are indispensable in the green market. Some ornamental tree species, such as Lonicera japonica, are more effective if they can be used properly.
